MID 039 - Machine Control Module
CID 3730 - Autonomous Stop Mode Indicator
FMI 05 - Current Below Normal
Illustration 1 | g03177815 |
This diagnostic code is recorded when the Input/Output module (I/O module) reads the current of the autonomous stop mode indicator (A-Stop mode indicator) circuit is below normal.
Test Step 1. CHECK THE INDICATORS USING A KNOWN GOOD INDICATOR.
Note: Use this procedure if only one of the three red indicators are not working when the keyswitch is cycled. If two or more indicators are not working, proceed to the next Step.
- Turn the keyswitch and the disconnect switch to the OFF position.
- Swap the indicator suspected to be bad with a known good indicator.
- Turn the disconnect switch to the ON position. While the swapped indicator is in view, turn the keyswitch to the ON.
Expected Result:
The new indicator is cycled on with the turn of the keyswitch.
Results:
- OK - The new indicator lights up with the turn of the keyswitch. The old indicator light failed in some way.
Repair: With the new indicator installed, check the status of the diagnostic code. If the code is no longer active, the old indicator light was faulty and the new indicator light is working properly.
STOP
- NOT OK - The new indicator does not illuminate with the turn of the keyswitch.
Repair: The problem is not with the indicators.
Proceed to Test Step 2.
Test Step 2. CHECK THE SIGNAL CIRCUIT FOR AN OPEN AT THE REAR INDICATOR.
- Turn the keyswitch and the disconnect switch to the OFF position.
- Disconnect the machine harness from the indicator lights.
- Disconnect the machine harness connectors J1 from the I/O module.
- At the machine harness connector for the rear indicator, install a jumper between contacts A and B.
- At machine harness connector J1, measure the resistance from the signal contact J1-61 (wire A661-BU(Blue)) to contact J1-60 (wire A657-WH(White)). Note the resistance.
Expected Result:
The resistance should be less than 5 ohms.
Results:
- OK - The resistance is less than 5 ohms. The machine harness is correct. Proceed to test step 4.
- NOT OK - The resistance is NOT correct. There is an open in the machine harness. The open is in wire A661-BU(Blue) between the rear indicator and I/O module part of the circuit. Refer to the full system schematic for more detailed information of the related connectors.
Repair: Repair the harness or replace the harness.
STOP
Test Step 3. CHECK THE SIGNAL CIRCUIT FOR AN OPEN AT THE FRONT INDICATORS.
- The keyswitch and the disconnect switch remain in the OFF position.
- The machine harness remains disconnected from the indicator lights and the I/O module.
- Using a jumper wire, measure the resistance of wire A661-BU(Blue) from the I/O module harness connector contact J1-61 to contact A of each front mode indicators. Note the resistances.
Expected Result:
The resistance should be less than 5 ohms for each measurement.
Results:
- OK - The resistance is less than 5 ohms. The machine harness is correct. Proceed to test step 4.
- NOT OK - The resistance is NOT correct. The open is in wire A657-WH(White) in the part of the circuit with the incorrect resistance. If the resistance is not less than 5 ohms for just one of the indicator wires, the open is in the section of wire that displayed the incorrect reading. If both indicator wires show incorrect readings, the open is most likely in the section of the circuit before the wire is split.
Repair: Repair the harness or replace the harness.
STOP
Test Step 4. CHECK IF THE DIAGNOSTIC CODE REMAINS.
- Inspect the contacts and clean the contacts of the harness connectors.
- Reconnect all harness connectors.
- Turn the disconnect switch and the keyswitch to the ON position.
- Clear all inactive diagnostic codes.
- Cycle the keyswitch position from ON to OFF to ON again and allow the machine electronic system time for the self check. The check will power the lights for 2 seconds.
- Observe the status of CID 3730 FMI 05 for the indicator.
Expected Result:
The CID 3730 FMI 05 for the indicator is NOT present.
Results:
- OK - The diagnostic code is NOT present. The diagnostic code does not exist at this time. The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.
STOP
- NOT OK - The diagnostic code has not been corrected. The ECM may have failed.
Repair: It is unlikely that the I/O module has failed. Exit this procedure and perform this CID 3730 FMI 05 again. If the cause of the diagnostic code is not found, replace the I/O module. Refer to Testing and Adjusting, KENR8394, "Electronic Control Module (ECM) - Replace".
